Specification of Letters Patent.

Patented' Feb. 4, 1919.

Application led. August 20, 1917. Serial No. 1817,800.

To all whom it may concern:

Be it known that I, WILLIAM J. BnRenNs, a citizen of the United Statesof America, and a resident of Muskegon, in the county of MuskegomStateof Michi an, have invented certain new \a`nd useful Improvements inMixing-Valves, of which the following is a specification.

This invention relates to that class of multiple valves adapted forconvenient manipulation by 'a single operating means to deliver water ofany required temperature for lavatory and like uses, and the presentimprovement has for its object To provide a compact, durable andeilicient structural formation and association of parts, whereby theuser is enabled to obtain allow of water of the desired temperature alc1, with the lateral in a ready and certain manner and with which theinflowing streams of hot and cold water are effectively mixed in athorough manner, as will hereinafter more fully appear.

In the accompanying drawings:

Figure 1, is `a plan view of the present valve.

Fig. 2, is an elevation of the same.

Fig. 3, is a horizontal section.

Fig. 4, is a vertical section.

Fig. 5, is a detail section of a modification.

Like reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates the central and Vmain casing ofthe valve, preferably of a circular shape, and having an approximatelyflat and integrally formed bottom web or wall 2 and a removable top wallor cap 3 provided with a packing gland 4 which receives the centrallyarranged operating spindle or stem of the valve mechanism.

5 and 6 designate counterpart radially disposed T shape valve casingsarranged at opposite sides of the main casing 1,' and preferably inaxial alinement with each other as shown. Said valvel casings 5, 6 arepreferably formed integral with the main casing branches 7 8 of therespective valve casings 5, 6 adapted for individual connection to therespective hot and cold water trunks 9 and 10 by union couplings l1 and12. Said trunks 11, 12 are preferably of the ordinary offset form shown.

13 and 14. designate closure caps fitting the outer ends of therespective valve casi lings 5, 6, and permitting ready access to thevalve mechanisms contained in said casings for repair and replacement.

15 and 16 designate removable screw bushingsl tting annular ledges' orpartitions inside the casings 5, 6, and'constituting the valve seatsthereof.

17 and 18 designate the movable valve members of the structure, of anyusual detail construction and having guidel stems 19, 20 moving in thecentral bores of the bushings 15, 16 with into the chamber of the maincasin .1 for operation by the mechanism hereina ter described. 21,21designate partitions arranged in transverse relation to the axis of thevalve members 17, 18, and formed with guide orices for movement of theinner guide stems 19, 20, of said valves. In the present improvement thepartitions 21, 21 constitute lateral extensions of the vertical wall ofthe l central chamber of the main valve casing 1,

and at the ends remote from the outlet neck 31 hereinafter described,said partitions are integrally connected to the wall of the casing 1,while at the ends next adjacent to said outlet neck, said partitions arespaced from the wall of the casing to provide narrow vertical passagesthrough which the passing waters are directed in a curved path towardeach other to commingle and attain a uniform mixture before reaching theoutlet neck i 22, 22 designate springs arranged in recesses in theclosure caps 13, 14, and having bearing against the valve members 17, 18to yieldinglyl maintain the same in a closed condition, inthe absence offluid pressure f which in present construction normally tends to 'closesaid valve members( 23 designates the central operating spindle or stemheretofore referred to as passing through the packing gland 4, andextending into the closed chamber of the main casing 1 aforesaid. At itsupper or outer end, the spindle 23 is provided with .an operating handle24 and an associated pointer 25, for indicating on a curved scale on theupper surface of the main casing 1, the position to which the handle 24is to be moved to obtain a iow of water of the desired temperature, asusual in the present class of valves.

26 designates a hub secured to the lower end of the operating spindle23, within the chamber of the main casing 1, and provided with a pair ofcam lugs 27 on its periphery. Said cam lugs 27 are irregularly spacedaround the circumference of the hub 26, as shown in Fig. 3, so thateither cam lug may operate its particular valve member in an independentmanner to effect a discharge of either het water or of cold water inaccordance with the particular turning adjustment of the hub 26, and sothat with a further turning adjustment, effecta mixed discharge of hotand cold Water.

l 28 designates a fixed stop lug in the interior ofthe main casing l,adapted for en# gagement in a sector shaped recess 29 in the hubV 26aforesaid, and adapted to limit the turning adjustment of said hub ineither direction.

30 designates a pair of intermediate arms or levers pivoted at one endin the interior of the main casing 1 andindividual to the respectivevalve stems 19, 20, and4 disp'sed between a valve stem and itsassociated cam" lug with said cam lug bearing against one side of thearm or lever and` with the valve stem bearing against the opposite sideof the arm o r lever, as illustrated in Fig. 3.

31 designates a tubular neck on the bottom wall 2 of the main casing 1to constitute the,v

outlet passage thereof, and in the preferred construction shown, saidneck is externally screw-threaded for the reception of a union thelowerend of a conical strainer now to coupling 32 by which a suitableoutlet nozzle 33, is secured to said tubular neck. The outlet nozzle' ispreferably of the horizontally adjustable type shown, and is formed withan enlarged chamber 34 at the intersection of its vertical andhorizontal passages.

35 `designates a hollow cap lnut closing an opening in the underside ofthe aforesaid chamber 34 and adapted to receive and hold be described.

mesme '-36 designates a strainer -of wire gauze or the like, and.preferably of the inverted cone form shown, with its lower and smallerend Aengaging in the cavity of the cap nut 35, to be held in properposition by such engagement of the parts. v

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is

1. Ina mixing valve, .the combination of a main casing having a centralcircular mixing' chamber, an eccentrically arranged bottom outlethousing and a pair of alined inlet housings se arated from the centralchamber by a pair of deflecting partitions which extend from portions ofthe circular Wall of the mixing chamber to spaced relation to opvidetangential passages next to lsaid wall, and a pair of longitudinallyalined valves arranged in said inlet housings, and means for operatingsaid valves, substantially as` set forth. l

2. In a. mixing valve, the combination of a main casing having a centralcircular mixing chamber, -an eccentrically arranged bottom outlethousing and a pair of alined inlet housings separated from the centralch-amber by a pair of deflecting partitions which4 extendk from portionsof the circular wall of the'mixingchamber'to spaced relation to opposedportions of said circular wall to provide tangential lassages next tosaid wall, and a pair ofp longitudinally alined valves arranged in saidinlet housings, and
